I also have had many positive and negative dealings with kinkos. The latest was yesterday afternoon, when I went to pick up a poster I had them print. It looked completely wrong and most of the gradients were missing. I gave them a PDF version 5. They only have acrobat 4, so information was getting lost. I even called them beforehand and asked what format - they wanted PDF. If what they WANT is a PDF, WHY WOULDN'T THEY HAVE THE LATEST VERSION OF ACROBAT??
Anyways, it was still readable, I could sort of use it, so the guy sold it to me for half off, and I told him to use the illustrator file instead - they have illustrator 10 (but not acrobat 5!?) He saved it as a PDF, opened that, and it looked fine. He said "it just worked on my machine here" (I had previously created the PDF directly from Illustrator10 as well). I looked at him and asked if he was actually this stupid - OF COURSE the illustrator PDF will look fine on his machine because all he has is Acrobat version 4 (meaning acrobat distiller version 4). ARRGH!! the imcompetence was astounding. He's making the new poster for half price, so in the end I'll just pay for one. One of the kids had the gall to say it was my fault because I saved it as version 5. I told him to go back to his copying, that I was talking to the manager - such attitude.

Actually though, if the planets are aligned, the file is a PDF, you give them a proof (which I forgot to do in the above rant), and specifically state what size it is trimmed down, and the manager isn't color blind (this guy was, he told me - and he wasn't joking, either) I don't know how they could screw it all up. But they find their ways - count on Kinko's to screw up the littlest things....
